sLPECIFICATION forming part of Letters Patent No. 741,289, dated October13, 1903.

Application filed August 9,1902. Serial No. 119.082. (No model.) I

method of constructing floors, while it par-' ticularly relates toso-called fireproof flooring and to the construction thereof. Its objectis to provide efiective, comparatively light weight, and economicalflooring of asplastic composition which shall whenset pos-' phalt, ofcement, or of substantially similar sess great vertical strength.

Referringto the accompanying drawings, wherein like reference-lettersindicate the same or corresponding parts, Figures 1, 3, 4, 5, '6, 7,8,and 9 are in part sectional views and in part elevations, andFig. 2 is abroken plan view.

Heretofore in the construction of doors of cement, of asphalt, or ofother composition a plank platform or centerfis erected or a swingsuspended beneath the place to be filled in such' manner as to close thelower end of the opening between the floor-beams,

' thereof. Owing to the weight of floors so and upon it cement, asphalt,or other composition is deposited and tamped down until the spacebetween the floorbeams is com pletely filled. When this filling hasbecome set, the center isremoved. :Floors so con-' structed areobjectionable, because of the excessive quantity of filling compositionnecessitated andthe consequent costand weight constructed it has beennecessary tosecure the floor-beams one to another by tie-bolts or.brace-beams at frequentintervals to prevent them from spreading and torelieve the walls by said weight...

of the building from the pressure occasioned By employing the device andmethod of constru'ctionof my iuventiona large saving in materials, cost,and weight is effected I without impairing the vertical strength of thecement or other filling; To these ends my invention consists in thefeatures of construction and. combination 'of the'I-beams A hereinaftermore fully described, and pointed out in the claims hereto annexed.fReferring particularly to Figs. 1, 2, and 3:

of the drawings, A, A', and Marc I-beams,

A and support the members B in upiii'ght position, as shown in Figs. 1and 3, and f lie substantially parallel to and separated I "acomparatively slight distance from each other, as shown in Fig. 2.

The filling D is thereafter deposited betweenand tamped about themembers B in such manner as to firmly embed them therein. When thefilling has become sufficiently set, the center may be removed. Where thedistance so arating the I-beam A'from the'Ibeain A is considerable-sayten feet-the members B should possess suflicient strength to'sustaiuthemselves and also to assist in sustaining the weight of the filling,-This may be offectedby forming said member of stitfer and stronger or ofheavier material than where the distance separating said I-beams is,say, three or four feet or by suitably corrugating the tubular part b.Again, auxiliary supporting meansmay be employed-as, for exa-mple,-thebars E (see Figs. Sand 9 )-pref- .erably laid in adirectionsubstantially at right-angles, to the longitudinal direction of themembers B and supported at their extremities, respectively, by thelowerflanges In Fig. 4 I have illustrated the member B in five differentforms. In; the form. shown at the extreme left of said figure thememberb is elliptical in cross-section. "In the form shown next to theriglit of the one last referred to; the member I) is also elliptical incross-section andprovided with peripheral tal, whereas in the form firstreferred to it is vertical. In the form shown in the center of thedrawing the member bis substantially of two pieces of sheet metal orother suitable square in cross-section. In the form'shown immediately tothe right of the one last referred' tobthe' member 11 is of diamond formin cross-section, and in the .form shown at the extreme right of thedrawing the mem v pieces permitting the hollow members to be ber b' isspirally corrugated. 1

In Fig. 5 the member B is shown formed material secured to each other byscrews, bolts, or other suitable securing means F.

In Fig. 6 the member B is also shown formed of two pieces of sheetmetalor other suitable material, which may or may not be secured the one tothe other, as preferred.

In Fig. -7 the construction shown is substantially that illustratedinFig. 5, the two however, being secured together by means of flanges G ofany suitable si'ze, form, and

number on the one piece, which enter suitable apertures or slots in theother piece.

In Figs. 8 and 9 the member B is not provided with a web and foot, 'butrests upon the bars E, ashereinbefore described.

It is obvious that the space between the beams A, A, and A may bepartially filled with cement, the member B be laid upon the top thereof,and thereafter the unoccupied space between the beams be filled to thedesired level and tamped down into proper place, that the member B maybe constructed in sections, and that the number, size,

and form of the various parts of my device may be greatly varied withoutdeparting from the principle of the invention.

In the forms of the member B, which have a web b and foot 11 Ihavedescribed them as being supported by the flanges of I-beams. It

will be understood ,thatthese members, of

whatsoever form they may be, may enter suit-.

able apertures inthe walls of a building or be otherwise suitablysupported, while it will be further understood that, if desired, saidfI-beams disposed transverse to said hollow members may be secured oneto another, it being only essential that a space occur between them'.The flanged foot-pieces b serve -5o as supports for the hollow members Bby rest-'- ing on the flanges of the'I-beams or in the. apertures in thewalls of the buildings,;so that said members will stand properlyinplace' when the concrete or cement is being filled in between them,said flanged footproperly separated from each other, so that theconcrete can be properly tamped about and beneath them, and thus form acement 6o ceiling to which plaster may readily be appliedwithoutrequiring special plaster holding or attachingmeans. Again, it will beunderstood' that the word cement. wherever, employed herein shallsignify any suitable floor-filling composition, such as asphalt,concrete, cement, &c.

f Having thus descrlbed my invention, what I claim as new, and desire tosecure by Letter Patent is- V r 1. In the fireproof construction 0tfloors,

ceilings, &c.',- the combination with a cement ,or concrete filling, ofa series of separated hollow members embedded in said filling andprovided with flanged foot-pieces, as 12 and suitable supportstransverse to saidhollow members on which said foot-pieces can restwhile thecement or concrete is being filled in to form the body of thefloor or ceiling. 2. In-the fireproof construction of floors, ceilings,&c., the combination with a cement or concrete filling, of a seriesof'separated' hollow membersembedded-in said filling and provided withfiangedfoot-pieces, as b and 8 5 members and against the flanges ofwhich I- ,beams the said foot-pieces can rest while the cement orconcrete is being filled in to form the body of the floor or ceiling.-
